Comparison
215/65 R16 vs 225/50 R17
Plus-sizing from 215/65 R16 to 225/50 R17 keeps overall diameter close to factory while opening room for a larger 17-inch wheel. This swap moves rolling diameter well outside the usual OEM tolerance.
Indicated speed will drift far enough that recalibration is worth considering. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. The larger wheel shows more of the brake hardware and tightens up the wheel-gap look. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.
Quick math: 225/50 R17 is 29.1 mm shorter than 215/65 R16, shifting the speedometer by -4.24%.

Speedometer impact
At a true 100 km/h, your dashboard will read 95.8 km/h after switching to 225/50 R17 — a -4.24% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by -14.6 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
